Question 250 Inline 6 Question

Hey guys, got a motor question about timing a 250 straight 6. I have a 1968 Chevy truck that had a early 250 straight 6 in it, but a 1977 250 straight 6 was dropped in a day before I bought it since the other motor went belly up. I drove it home and it ran like crap, so I did a little looking around. The distributor was bolted down enought to keep it in place but it was sliding all around when I was on the road. I am freshening things up and figured that timing it would be in my best interests. Here is my dilemma. Apparently in 1977 there were two applications of the 250, heavy and light duty. I would imagine that the heavy means truck, and the light means car....The heavy needs to be set at 12 degrees before TDC, and the light at 6 degrees before TDC. I have no idea what this motor came out of, what can I do to find out? Thanks,
Josh

Good judgment comes from experience, and experience, well......that comes from bad judgment.


1968 Chevy C-10 "Longshot": Bought used from my Uncle George in 1994 and proceeding to beat the hell out of it for 4 years. Sold it. Bought it back, dumped an ungodly amount of money into it since then.
